Did he bring his own formation or new tactics to the team - hardly.
Were there new players he needed to get in to adapt to the team - no, even chiesa was barely in the team.

He basically jumped into a A380 that was cruising at attitude, left it at auto pilot and won us the title. Granted, we have to thank Arsenal and Manchester City for having a massive dip of form at the same time.

But the cracks were showing. There were two BIG games where his tactics and knowledge and management skills were desperately needed. At home to PSG, and also the League Cup final against Newcastle. These two games was where he was found out to be lacking.

And players, especially elite players like Salah know when to look up to a Manager who knows what he is doing, and one who does not. Before these two games, Salah was firing on all cylinders, gunning for the Balon D'or. Even with the PSG defeat and being out of the CL, Salah would have still been a favorite if he has continued his form all the way till the end of the season. This did not happen. And it was not just Salah, the whole team, the malaise for LFC did not start this season, it started last season.

The early form, and luck, and the Jota factor drove us for the first few games on this season. The Isak situation did not help, but we still won ugly, late goals covered up the cracks. The silly transfer window where we replaced players who worked hard like Diaz, Nunez, even Elliot just never made any sense.

Getting so many new players in, and still playing a system that was still essentially the system Klopp built up from scratch - a system that desperately needs players to work hard, and press high and chase down every ball - with new players is not easy, but Slot just stuck with it, throwing square pegs in round holds, and just hoping it works is the ethos of a manager who is severely out of depth, trying to play a system that was never his to begin with.
